Last year, The Intercept published documents detailing the NSA's SKYNET programme. According to the documents, SKYNET engages in mass surveillance of Pakistan's mobile phone network, and then uses a machine learning algorithm on the cellular network metadata of 55 million people to try and rate each person's likelihood of being a terrorist.
Patrick Ball—a data scientist and the director of research at the Human Rights Data Analysis Group—who has previously given expert testimony before war crimes tribunals, described the NSA's methods as 'ridiculously optimistic' and 'completely bullshit.'

"You have something special and important here. Somehow you manage to teach and suggest and introduce the reader to concepts in a way that feels inclusive. Like, we're thinking about it together. Partly it might be because the subject, bottom-up, is innately understood by all of us and so it feels like you're stirring up stuff we already know. But also I think it's because you truly are practiced at connection consciousness and so it's natural for you (I'm guessing) to write about it with a desire to include us. As a reader I was learning more because it feels like you're inviting me to think with you."
